NEW YORK (WPVI) — Two Bucks County, Pennsylvania, men who allegedly brought explosives to a protest outside New York City’s mayoral mansion said they were inspired by the Islamic State extremist group, a court complaint said.
Emir Balat, 18, and Ibrahim Kayumi, 19, were being held without bail after their arraignment Monday on charges that include attempting to provide material support to a terrorist organization and using a weapon of mass destruction. Their lawyers didn’t argue for bail, but could do so later.
The homemade devices, which did not explode, were hurled Saturday during raucous counterprotests against an anti-Islamic demonstration led by Jake Lang, a far-right activist and critic of New York Mayor Zohran Mamdani, a Democrat and the first Muslim to hold the office.
Images from the federal criminal complaint show Balat with an improvised explosive device in hand outside the mayor’s residence, according to prosecutors.
Another image showed Kayumi, on the right, allegedly handing an IED to Balat, seen on the left.
The men said nothing during the brief proceeding, but Kayumi smirked and looked over at Balat as the judge read part of the complaint that said that they were acting in support of the Islamic State group.
Balat stared ahead at the defense table.
According to the complaint, Kayumi blurted out, as he was being arrested Saturday, that “ISIS” was the reason for his conduct.
Balat later told authorities that he had pledged allegiance to the extremist group, and Kayumi asserted that he was affiliated with the Islamic State group, the complaint said.
Officers asked Balat whether he was aiming to accomplish something akin to the bombing of the Boston Marathon in 2013, when two pressure-cooker bombs exploded near the finish line, killing three people and wounding hundreds more.
“No, even bigger,” Balat replied, according to the complaint.
In court, Kayumi’s lawyer, Michael Arthus, pointed to the extensive publicity surrounding the case and asked that prosecutors avoid saying anything that could prejudice potential jurors.
Balat’s lawyer, Mehdi Essmidi, said outside the court that his client was three classes away from graduating from high school.
Balat is a student at Neshaminy High School, Action News has learned, while Kayumi is a 2024 graduate of Council Rock High School North.
On Sunday, the FBI raided Balat’s home in Langhorne and Kayumi’s home in Newtown.
Both of the neighborhoods were quiet on Monday. Action News spoke with one neighbor who knows Balat’s family. She said she knew them as a loving family, and she was stunned when she found out about this.
Balat’s family declined to comment. Action News was unable to reach Kayumi’s family for a response.
New York City officials have confirmed that federal paperwork is now being filed in a terrorism case against two men from Bucks County, Pennsylvania.
Chopper 6 was overhead on Monday afternoon as authorities searched a storage facility on the 500 block of Flowers Mill Road in Middletown Township. Investigators have not revealed more on the search, but we’re told it’s related to this investigation.
Police search storage facility in connection with terror plot
An automated license plate reader captured the suspects entering New York City from New Jersey less than an hour before the noontime attack, according to the complaint. Kayumi’s mother filed a missing person report saying she last saw him around 10:30 a.m. Saturday.
“They crossed the George Washington Bridge with a license plate reader ping at 11:36 a.m. on Saturday, parked in front of 48 East End Avenue between 81st and 2nd streets at 12:05 p.m. and walked to the protest. They ignited and threw the devices at approximately 12:15 p.m. and were immediately arrested thereafter,” said NYPD Commissioner Jessica Tisch
The suspects’ vehicle – registered to one of Balat’s relatives – was discovered Sunday a few blocks from where they were arrested. A search of the car turned up a fuse and a metal can, along with a written list of chemical ingredients and components that could be used to build explosives, the complaint said.
No ties to Iran war are identified
Speaking outside the mayoral residence, Gracie Mansion, on Monday morning, Mamdani said Balat and Kayumi “traveled from Pennsylvania and attempted to bring violence to New York City.”
Mamdani and his wife weren’t home during the protest.
Tisch said there are no indications that the men’s alleged activities were connected to the ongoing war in Iran. The Islamic State is a group of Sunni extremists; Iran’s population is almost entirely Shiite, the other main religious community within Islam.
While Mamdani and Tisch briefed reporters Monday, Lang heckled from outside the Gracie Mansion gates.
The attack unfolded in a chaotic scene
Lang’s sparsely attended protest Saturday drew a far larger group of counter-demonstrators. Amid the faceoff, Balat tossed a jar-sized device that contained the explosive TATP into the crowd, the complaint said.
It also contained a fuse, plus an exterior layer of duct-taped nuts and bolts, the complaint said.
The device extinguished itself steps from police officers.
According to the complaint, Balat then ran down the block and collected a second, similar device from Kayumi, dropped it near some police officers and tried to run away, the complaint said.
Police tackled Balat and soon arrested him and Kayumi.
The scene had grown chaotic even before the devices were thrown. Police said one person involved in the anti-Islam protest, Ian McGinnis, 21, was arrested after pepper-spraying counter-protesters.
McGinnis, of Philadelphia, was released without bond after pleading not guilty Sunday to assault and aggravated harassment in a New York court, records show. A message seeking comment was left Monday for his attorney.
Three others were taken into custody but were released without charges.
After the Jan. 6 insurrection at the U.S. Capitol, Lang was charged with assaulting an officer with a baseball bat, civil disorder and other crimes.
He was later freed from prison as part of President Donald Trump’s sweeping act of clemency. Lang recently announced that he is running for U.S. Senate in Florida.
Earlier this year, he organized a rally in Minneapolis in support of Trump’s immigration crackdown, drawing an angry crowd of counter-protesters who quickly chased him away.
